We were not setting the `historical` flag correctly for
messages fetched via `json_fetch_raw_message` when used didn't
have any UserMessage.
Extended relevant tests to fetch check message flags too.
This avoids an error when a user has already muted the new topic name.
We do this by ignoring duplicates, rather than catching the
IntegrityError, because this edit happens in a transaction, and that
would abort the transaction.
Our original implementation of moving muted topic records when a topic
is moved took a shortcut of treating all change_later usage as
something with intent to move the whole topic.
This works OK when moving the whole topic via this interface, but not
when moving a last off-topic message in the topic.
Address this by changing the rule to match the existing
moved_all_visible_messages variable.
Previously, Attachment.is_realm_public and its cousin,
Attachment.is_web_public, were properties that began as False and
transitioned to True only when a message containing a link to the
attachment was sent to the appropriate class of stream, or such a link
was added as part of editing a message.
This pattern meant that neither field was updated in situations where
the access permissions for a message changed:
* Moving the message to a different stream.
* Changing the permissions for a stream containing links to the message.
This correctness issue has limited security impact, because uploaded
files are secured both by a random URL and by these access checks.
To fix this, we reformulate these fields as a cache, with code paths
that change the permissions affecting an attachment responsible for
setting these values to the `None` (uncached) state. We prefer setting
this `None` state over computing the correct permissions, because the
correct post-edit permissions are a function of all messages
containing the attachment, and we don't want to be responsible for
fetching all of those messages in the edit code paths.
Add support for moving MutedTopic entries to another stream where
the user has access to shared history in both streams and
`propagate_mode != "change_one"`.
Also, we delete them the current user does not have access to the
target stream.
Previously, when a topic was edited (including being resolved), it
would become unmuted for any users who had muted it, which was
annoying.
While it's not possible to determine the user's intent completely,
this is clearly incorrect behavior in the `change_all` case, such as
resolving a topic.
The comments discuss some scenarios where we might want to enhance
this further, but this is the best we can do without large increases
in complexity.
Fixes#15210.

Previously, this URL just returned the `raw_content` field. It seems
cleanest to just make it a single-message variant of GET /messages,
deprecating the only format.
Since we've changed the database to contain these new fields, we just
need to stop dropping them in the API code.
This also changes the public API to match the database format again
by removing `prev_subject` from edit history API.
Adds an API changelog feature update for the renamed `prev_subject`
field (to `prev_topic`) and new fields (`topic` and `stream`)
in the message `edit_history`.
Also, documents said `edit_history` in the `MessagesBase` schema
in the api documentation, which is used by the `/get-messages`,
`/get-events` and `/zulip-outgoing-webhooks` endpoints.
Fixes#21076.

Now that we have code to support reading prev_topic, this is no longer
necessary.
We'll want to deploy this change to production before running the
migration to remove prev_subject from edit history entries, so that
prev_subject can be fully purged from the database.
We modify the message_edit_history marshalling code so that this
commit does not change the API, since we haven't backfilled the data
yet.
FormattedEditHistoryEvent, introduced in the previous commit, doesn't
directly inherit fields from EditHistoryEvent, so no changes are
required there.
Various backend tests use the `PATCH /messages/{msg_id}` endpoint.
For that endpoint, the message ID is encoded in the URL path and
ignored if provided as a parameter in the the query.
Verified that the tests were providing the same message ID to both
the path and then removed the ignored parameter in the query.
The message ID is encoded in the URL, not the PATCH parameters, so
this argument was ignored. I verified that it appears to have always
matched the value present in the URL.
The new logic better matches reasonable user expectations, that if you
move all the messages, that's a whole-topic move, regardless of which
propagation mode you selected.
When moving only part of a topic, it's useful to display that
information to users in these notifications so that it's clear what's
happening.
The most important consequence is actually just increasing confidence
that when you see that the whole topic was moved, that's accurate.
Substantially modified by tabbott.
Fixes#20575.
Previously, users found it annoying that the automated "Resolve topic"
notifications triggered an unread for everyone in the stream; this
discouraged some users from using the feature on older threads for
fear of being annoying. We change this to a better default, of only
users who participated in the topic (via either messages or reactions)
being eligible for the new message being unread.
We will likely want to create global and stream-level notifications
settings to control this behavior as a follow-up -- some users, like
me, might prefer the simpler "Always unread" behavior in some streams.
Note that the automated notifications that a topic was resolved will
still result in the topic being moved to the top of the left sidebar.
This would be somewhat difficult to change, since the left sidebar
algorithm just looks at the highest message ID in the topic.
Fixes#19709.

Under the unicodedata distributed with Python 3.6, some Emoji are
classified as `Cn`, and not `So`:
```
$ unicode 1f929 --long
U+1F929 GRINNING FACE WITH STAR EYES
UTF-8: f0 9f a4 a9 UTF-16BE: d83edd29 Decimal: 🤩 Octal: \0374451
🤩
Category: So (Symbol, Other); East Asian width: W (wide)
Unicode block: 1F900..1F9FF; Supplemental Symbols and Pictographs
Bidi: ON (Other Neutrals)
$ python3.6 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
Cn
$ python3.7 -c 'import unicodedata; print(unicodedata.category("\U0001f929"))'
So
```
Drop `Cn` from the list of excluded Unicode character classes, and
replace it with an explicit list of the 66 non-characters, which are
invariant.

An explanatory note on the changes in zulip.yaml and
curl_param_value_generators is warranted here. In our automated
tests for our curl examples, the test for the API endpoint that
changes the posting permissions of a stream comes before our
existing curl test for adding message reactions.
Since there is an extra notification message due to the change in
posting permissions, the message IDs used in tests that come after
need to be incremented by 1.
This is a part of #20289.
We now complain if a test author sends a stream message
that does not result in the sender getting a
UserMessage row for the message.
This is basically 100% equivalent to complaining that
the author failed to subscribe the sender to the stream
as part of the test setup, as far as I can tell, so the
AssertionError instructs the author to subscribe the
sender to the stream.
We exempt bots from this check, although it is
plausible we should only exempt the system bots like
the notification bot.
I considered auto-subscribing the sender to the stream,
but that can be a little more expensive than the
current check, and we generally want test setup to be
explicit.
If there is some legitimate way than a subscribed human
sender can't get a UserMessage, then we probably want
an explicit test for that, or we may want to change the
backend to just write a UserMessage row in that
hypothetical situation.
For most tests, including almost all the ones fixed
here, the author just wants their test setup to
realistically reflect normal operation, and often devs
may not realize that Cordelia is not subscribed to
Denmark or not realize that Hamlet is not subscribed to
Scotland.
Some of us don't remember our Shakespeare from high
school, and our stream subscriptions don't even
necessarily reflect which countries the Bard placed his
characters in.
There may also be some legitimate use case where an
author wants to simulate sending a message to an
unsubscribed stream, but for those edge cases, they can
always set allow_unsubscribed_sender to True.
This commit adds code to check whether a user is allowed to use
wildcard mention in a large stream or not while editing a message
based on the realm settings.
Previously this was only checked while sending message, thus user
was easily able to use wildcard mention by first sending a normal
message and then using a wildcard mention by editing it.
It is confusing to have the plan type constants not be namespaced
by the thing they represent. We already have a namespacing
convention in place for constants, so we should use it for
Realm.plan_type as well.
`rendered_content` in historical messages may be empty; examining the
history of them may thus require diff'ing two empty strings, which
itself produces an empty string.
Use `lxml.html.fragment_fromstring` to be able to successfully parse
these, rather than 500.
Part of #19559.
Since the calls to the translation function `_()` are made outside
of the `send_message_moved_breadcrumbs` function, these strings are
translated outside of the `with override_language` block, leading to
translated strings even when we don't intend them to be translated.
We now use gettext_lazy with appropriate testing to avoid this.
This commit replaces 'allow_message_deleting' boolean setting
with an integer setting 'delete_own_message_policy'. We have a
separate dropdown now for deciding which user-roles can delete
messages sent by themselves and the time-limit setting droddown
is different.
This new setting has two options - everyone and admins only. Other
options including moderators will be added further.
We also remove the "Never" option from the original time-limit
dropdown, as admins are always allowed to delete message. This
never option resembled the case of only admins being allowed to
delete but this state is now resembled by setting the dropdown
to "admins only" and we also disable the time-limit dropdown in
this case as admins are allowed to delete irrespective of limit.
Note, this setting is only for deleting messages sent by the
deleting user themselves, and only admins are allowed to delete
messages sent by others as before.
We make zero invalid value for message_content_delete_limit_seconds and
for handling the case of "Allow to delete message any time", the API-level
value of message_content_delete_limit_seconds is "anytime" and "None"
as the DB-level value. We also use these values for message retention
setting, so it helps maintain consistency.
This adds a new class called MessageRenderingResult to contain the
additional properties we added to the Message object (like alert_words)
as well as the rendered content to ensure typesafe reference. No
behavioral change is made except changes in typing.
This is a preparatory change for adding django-stubs to the backend.

We already have this data in the `flags` for each user, so no need to
send this set/list in the event dictionary.
The `flags` in the event dict represent the after-message-update state,
so we can't avoid sending `prior_mention_user_ids`.
Previously, it was possible for an unusual series of topic-edit
actions to result in Notification Bot reporting that a topic was
marked as resolved that had already been marked as resolved, etc.
A buggy client might send a message_edit request to change the topic
field, sending the current topic as the new value. Previously, we
would treat that as a normal request to edit the topic; now we act as
though the API request had not requested a topic change. In the
common case that only the topic was in the edit request, this now
results in an error that should help client implementations identify
their bug.
This fixes a bad interaction with the "unresolve topic" logic, which
assumed that upstream logic had verified that the topic was actually
changing.
This is a prep commit for adding members, full members and moderator
options to edit_topic_policy. As we will be adding tests for these
options, we will need to add a login statment repeatedly and this
helps us in avoiding that.
This is a prep commit for adding moderators, full
members and member roles in edit_topic_policy.
As we add these new options, we will add tests with
user with all these roles and thus we would need to
login as iago repeatedly when changing parameters.
So, to avoid this we instead login as Iago in
set_message_editing_params itself.
This commit replaces the allow_community_topic_editing boolean with
integer field edit_topic_policy and includes both frontend and
backend changes.
We also update settings_ui.disable_sub_settings_onchange to not
change the color of label as we did previously when the setting
was a checkbox. But now as the setting is dropdown we keep the
label as it is and we don't do anything with label when disabling
dropdowns. Also, this function was used only here so we can safely
change this.
